The vertices are M(-4, 0) N(0,5) O(10,-3)

I have an answer already, but I'm looking to verify it.

a.) One number is 3 less than another. If 7 times the smaller number minus 3 times the larger number is 7, find the two numbers.

b.) Complete the ordered pairs for the equation y = 5x + 5.
(?,0), (4/5,?), (0,?), (-4/5,?)

c.) Find the slope of the line passing through the points (–2, 7) and (8, –1).

d.) An employee who produces x units per hour earns an hourly wage of y = 0.75x + 9 (in dollars). Find the hourly wage for an employee who produces 14 units per hour.

Thanks evrybody who helps out!!

HW 1: Suppose we have two regular tetrahedrons, one blue and one red, and the vertices of each are numbered 1 through 4, so that when we roll each tetrahedron, each of the four numbers is equally likely to appear as the top vertex. Such tetrahedrons are essentially four-sided dice. How many possible outcomes are there when we roll these two dice?


HW 2: What is the probability that both die will show the same number?


HW 3: What is the probability that the sum of the numbers on the dice will be 3?


HW 4: What is the probability that at least one of the dice will show a 1?


HW 5: A school has a fund-raising raffle. 500 tickets are sold for $10 each. One grand prize of $1000 is awarded to the w inning ticket. What is your probability of winning the grand prize if you buy 10 tickets?

HW 6: If, in problem 5 there are two grand prizes, what are your chances of winning at least one of the two prizes if you buy 10 tickets? (Hint: think about this carefully. It may help to think about how you would calculate your chances of not winning either prize first.)

HW 7: Suppose a dart board is divided into three pie-shaped sections emanating from the center. The central angle of section A is 45 degrees, of Section B is 135 degrees, and Section C is 180 degrees. Given that a dart lands somewhere on the board, we assume that it is equally likely to land in at any given point on the board. What is the probability that it will land in each of the three sections?

HW 8: What is the probability that, if we throw three darts, they will all land in Section A?

HW 9: What is the probability that if we throw two darts, one will land in each of sections A and C?

HW 10: If you draw two cards from a full deck of 52 standard playing cards, what is the probability that they will be a pair?


HW 11: If you draw two cards from a full deck of 52 standard playing cards, what is the probability that they will be a pair of Jacks?

I cant figure any of these out!!
1)Find dy/dx if y=sin(x+y)
2)differentiate: y=csc^2(x)+cot^2(x)
3)differentiate: y=sin^2(t)-cos^2(t)
4)Find dy/dx if (x^2)-(y^2)=2xy
5)Find dy/dx for the equation (x^3)-(2(x^2)y)+3xy^2=38
6)Find dy/dx, then evaluate the derivative at the point (0,2): (x^2)-(2xy)=(y^2)-4
7)Find an equation for the tangent line to the graph of f(x)=√(x+1) at the point where x=3.8)
8)Find f '(x) for f(x)=2(x^2+5)^7

Calculate the enthalpy change for the reaction shown below.
BrCl(g) Br(g) + Cl(g) H = ?

Use the following data.
Br2(l) Br2(g) H = 30.91 kJ
Br2(g) 2 Br(g) H = 192.9 kJ
Cl2(g) 2 Cl(g) H = 243.4 kJ
Br2(l) + Cl2(g) 2 BrCl(g) H = 29.2 kJ

I really thought it was 107.1 but that was wrong. HELP!?

Hi,

I seem to be having problems know when/how to use Hensel's Lemma and the Chinese Remainder Theorem... Any tips? Good advice? My midterm is on Monday, and I just seem stuck!

Thanks!

If sinhx = (e^x - e^x)/2 & coshx = (e^x + e^-x)/2

I think you're supposed to substitute the equivalents of sinhx and coshx into the orig. equation. I just think I'm messing up in the algebra.

the equation is cos(x+1) + 1 = sin(xy²)
the x-coordinate is 2 and the y-coordinate is 1.8.

1) find the slope of the tangent line.
2) give an equation of the tangent line and solve it for y.

100 pennies are on a table, and exactly 10 are tails. With
your eyes closed, separate them into two groups so that
each group has the same number of tails. Her answer is to
take any 10 pennies and turn them over; that is group 1,
and it has the same number of tails as the remaining 90.

Why does this answer work?
